Thermal Dispersion

Thermal Dispersion technology is based on the principle that the amount of heat absorbed by a fluid is proportional to its mass flow. Thermal dispersion (mass) flow measurements are achieved by using two temperature sensors and a heat source located in a flow stream. By measuring the energy (heat) added to the flow stream and measuring the corresponding temperature change, mass flow can be derived.
Thermal dispersion is a highly reliable and robust method for accurately measuring airflow velocities in today’s HVAC applications.

Differential Pressure

Differential Pressure technology is commonly used to measure fluid velocity due to their well-defined relationship. The square root of the differential pressure is proportional to the flow rate velocity of the fluid. In ducted systems the total pressure consists of the velocity pressure and static pressure. Velocity pressure cannot be measured directly; it must be derived. By measuring the total and static pressures in a duct, the velocity pressure can be obtained by subtracting static pressure from total pressure. This is achieved in practice by directly measuring the differential pressure between the two.

Transmitters & Controllers

The job of a transmitter is to receive a signal and transmit it to a recipient. If the recipient is lucky, the signal will arrive exactly as it was transmitted allowing the controller, if there is one, to do its job properly. Depending on your application, high accuracy may or may not be important to you. In the HVAC world transmitter accuracy is of the upmost importance, not only because you are dealing with the air people breathe, but also because you are responsible for maintaining building health. Make sure you choose the right transmitter and/or controller for your application.

Office Buildings

People who work in a healthy and comfortable environment are more productive in their jobs. Make sure that these spaces have adequate outside air flow, comfortable community temperatures, and are properly pressurized. A happy and healthy associate is a productive associate.

Industrial Spaces

Excellent indoor air quality can be difficult to achieve in a factory or industrial space due to a variety of oils, chemicals, machinery, etc. that are present in the buildings. Proper airflow throughout the building is crucial to not only a healthy environment, but a productive and efficient environment as well.

Condominium Buildings

Keep owners and tenants healthy and comfortable by making sure that these spaces have adequate outside air flow and are properly pressurized. Those condo association meetings are no fun as it is. Taking airflow problems off the agenda is a good thing.
